Comparative Evaluation Studies of Different Species of Pleurotus for Radial Growth, Biomass and Yield Parameters

Aim: This study was undertaken with the major objective of determining the best yielding mushroom among the three species of Pleurotus spp. i.e., P. florida, P. djamor and P. sajor caju.

Study Design: The experiment was laid out in Completely Randomized Design (CRD) with five treatments in three replications.

Place and Duration of Study: The experiment was conducted at Plant Pathology laboratory of Dau Kalyan Singh College of Agriculture & Research Station, Bhatapara, Chhattisgarh.

Methodology: Pure culture was prepared from the spawn and then observations were recorded for radial growth and Biomass by subculturing the isolates in freshly prepared Potato Dextrose Agar (PDA) medium. Then, after making spawn of all isolates, they were cultivated for determining the yield of particular isolates.

Results: The results indicated that P. sajor caju is significantly superior with Radial growth -78 mm, Biomass - 4.884 gm & Yield- 804 gm followed by P. florida and then P. djamor respectively.

Conclusion: The results obtained from the present study can help the mushroom growers in selecting superior isolate for cultivation, leading to enhanced quality of spawn thereby increasing the yield of this nutritious & medicinal crop
